How hard will be the accountability on the Day of Judgement? Will we be questioned about every action or will we be judged based on the overall book of deeds?
From the Qur'an and hadith, it is understood that every action is recorded, known, visible, and considered on the Day of Judgment, in light of the circumstances (for instance, intention, accidental deeds, and so forth), except for things which have been genuinely forgiven and which are erased.
However, we hope for Allah's mercy in accounting!
